ROTARY ENGINE.

Application filed November 26,1910.

Specification of Letters Patent.

Patented Aug. 15, 1911.

Serial No. 594,385.

To all whom it may concern:

Be it known that I, J OSEPH GoUonoN, a citizen of the United States,residing at Baltic, in the county of Houghton and State of Michigan,have invented a new and useful. Rotary Engine, of which the following isa specification.

This invention relates to rotary engines and consists in the novelconstruction and arrangement of its parts as hereinafter shown,described and claimed.

The object of the invention is to provide a reversible engine of therotary type which is provided with a series of link controlled valvegears which in turn are operatively connected with the engine shaft,means being provided for manually shifting the valves to change thedirection in which the engine shall rotate the said means includingmechanism for closing one or the other of the exhaust ports of theengine. That is to say when the cut-off valve which controls the steamto drive the engine in one direction is held closed over its port itscotiperating exhaust valve is also closed. Thus when the engine is torotate in one direction, the cut-off and exhaust valves at one side ofthe piston are closed while the valves at the other side are open andwhen the engine is to rotate in the opposite direction, the firstmentioned valves are open while the last mentioned valves are closed.The parts of the valve gears are manually shiftable with relation to thelinks whereby the movement of the cut-off valves may be controlled.

In the accompanying drawings :Figure l is a side elevation of the enginewith parts broken away. Fig. 2 is a side' elevation of the engineviewing the same at a right angle to the side illustrated in Fig. 1 withparts of the side in section. Fig. 3 is a top plan view of the engine.Fig. 4: is a perspective View of the piston of the engine.

The engine includes a casing 1 in which is j ournaled a shaft 2 a flywheel 3 being mounted upon the said shaft. A piston 4 is located in thecasing -1 and is fixed to the intermediate portion of the shaft 2. Thepiston 4 is provided in its periphery and in the vicinity of itsopposite ends with steam cavities 5 and 5. These cavities are deeper atone end than at the other and in fact at the shallow end they vanish inthe periphery of the piston. The cavities 5 and 5" are alike except thatthe deep end portions of the cavities 5 are disposed in the oppositedirection from the deep end portions of the cavities 5. The casing 1 isprovided with steam inlet ports 6 and 6 and steam exhaust ports 7 and 7.The cavities 5 and 5 are arranged to move under-the inlet ports and overthe exhaust ports. A steam chest 8 is formed in the upper part of thecasing 1 and a steam supplypipe 9 communicates with the said steamchest. The ports 6 and 6 lead from the interior of said chest to thechamber in which the piston 4 is located. Valves 9 and 9 are located inthe chest 8 and are arranged to move over the ports 6 and 6respectively. Operating rods 10 and 10 are connected with the valves 9and 9 and project through the sides of the casing 1. Levers l1 and 11are fulcrumed at sides'of the casing 1 and their lower ends arepivotally connectedwith the outer ends of the rods 10 and 10. Bars 12and 12 are pivotally connected at their outer ends with the upper endsof the levers 11 and 11 and the said bars are provided at their innerends with pivoted blocks 13 and 13 respectively. Links 11 and 14 arepivotally mounted on standards 15' and 15 respectively which are mountedupon the top of the casing 1 and the blocks 13 and 13 are slidablymounted in the said links.

'A shaft 16 is journaled in standards 17 which are mounted upon the topof the casing 1 and an operating handle 18 is fixed to the said shaft. Asegment 19 is located adj acent said lever 18 and the lever is providedwith a spring pawl 20 adapted to engage the said segment whereby thesaid lever is held in an adjusted position. Links 21 and 21 arepivotally connected at their lower ends with the intermediate portionsof the bars 12 and 12 respectively and at their upper ends the saidlinks 21 and 21- are pivotally connected with arms 22 and 22 which inturn are fixed at their inner ends to the shaft 16 and project beyondthe opposite side thereof.

Eccentrics 23 and 23' are mounted upon the shaft 2 at the opposite sidesof the casing 1 and the deep portion of the eccentric 23 projects beyondthe opposite sides of the shaft 2 from the deep portion of the eccentric23. The eccentrics 23 and 23 are suprounded by eccentric straps 24 and24 and rods 25 and 25 are connected at their lower ends with the straps24 and 2a in the usual manner. The upper ends of the pitman rod 25 and25 are pivotally connected with the inner ends of the arms 26 and 26'respec tively and the said arms 26 and 26 are fixed to shafts 27 and 27respectively which are journaled in standards 28 and 28 located at thetop of the casing 1. Arms 29 and 29 are fixed at their upper ends to theshafts 27 and 27 respectively and extend downwardly approximately atright angles to the arms 26 and 26. Bars 30 and 30 are pivotallyconnected at their outer ends to the lower ends of the arms 29 and 29respectively and at their other ends the said bars 30 and 30 arepivotally connected with the links 14 and 14: respectively.

Valves 31 and 31 are located in the exhaust passages 7 and 7respectively and are operatively connected with rods 32 and 32'respectively. A lever 33 is fulcrumed to the side of the casing 1 andits ends are connected with the upper ends of the rods 32 and 32. Thelower end of a rod 34 is pivotally connected with the lever 33 at oneside ""of the fulcrumed point of the latter and the upper end of the rod34 is pivotally connected to the end of an arm 35 which in turn isrigidly fixed upon the shaft 16. By this arrangement a valve gear isprovided which may be manually adjusted in connection with the pivotedlinks to cause one or the other of the valves to move to a greater orless extent over the port that it governs and by reference to thedrawings it will "be seen that the parts are so proportioned andarranged that when one valve is at a state of rest or approximately soover the port that it governs the other valve is movable over that portwhich it governs. This 1 is for the reason that when the shaft 16 is Tmoved longitudinally and the lever 33 is rocked upon its fulcrum. Thearrangement of the rods 32 and 32 with relation to the valves 9 and 9 issuch that when for instance the rod 32 closes the valve 31 in theexhaust passage 7 the valve 9 is uncovered from its port or is permittedto move to uncovered position with relation to the same while the valve9 is held in covered position over its port 6. On the other hand when '3the valve 31 in the exhaust passage 7 is closed the valve 9 is permittedto move over its port 6 while the valve 9 is held in closed positionover the port 6. By this arrangement the steam or fluid pressure canpass through one side of the casing 1 while the valves at the oppositeside of said casing are closed and vice versa. Inasmuch as the deepportions of the cavities 5 and 5 in the piston 4 are disposed inopposite directionsv upon the periphery of the said piston it will bereadily understood that the steam when projected through thetangentially disposed duct 6 into the cavities 5 will impact theshouldered portion thereof and rotate the piston 1 in one directionwhile when the steam is projected oppositely into the cavities 5 toimpact the shouldered portion thereof to rotate the piston 4 in anopposite direction. Therefore it will be seen that means is provided forreversing or changing the direction in'which the engine shaft isrotated.

Any form of impact receiving and pressure fluid expanding blades may beused upon the piston 4, the essential feature of the invention being thearrangement of the inlet and exhaust valve operating mechanism operatedfrom the main shaft of the engine.

Having thus described the invention what I claim as new and desire tosecure by Letters Patent is I 1.
